In a documentary to air on the ABC on Sunday night, Sergeant Dods and Senior Constable Blundell say they still relive the shooting.

"We went to the front of the car and I think Dodsy first gave us the command to show your hands, show your hands," Senior Constable Blundell said.

"They [the police force] teach us to withdraw. They don't teach us to stand our ground and confront people, or to force that kind of confrontation."

Sergeant Dods added: "He wouldn't obey, and eventually he did and produced two large knives, and held them up."

Senior Constable Blundell said it was at this moment he realised he might have to shoot the 15-year-old.

"Because there was nothing else that I could do and I had to protect Dodsy," he said.

I do go over it every day, I still think what we could have done to make him back down

Sergeant Dods said: "I do go over it every day ... I still think what we could have done, to make him back down."

It is the first time the officers have talked about the shooting since appearing at the inquest in 2010.

After a marathon inquest into the shooting, Victorian Coroner Jennifer Coate said the case "shocked and bewildered" the Victorian community, and the teenager's death should serve as "clarion call" to Victoria Police.

She rejected the notion that the officers' response was disproportionate and found that at least one of their lives was in immediate danger.

The full interviews with Colin Dods and Richard Blundell can be seen on ABC1 on Sunday night, at 9:30pm.
